.- Guadalajara Jalisco, Zacatecas and Durango are the only entities of that country, apart from cases of influenza A-H1N1, reported cases of influenza A in seasonal ... off-season, said Miguel Ángel Fernández Lezana, director general of the National Center for Epidemiological Surveillance and Disease Control (Cenavece) of the Federal Ministry of Health. A "rather unusual" to be investigated further, he admitted in an interview via telephone with the public.


Lezana Fernandez denied that the National Institute of Epidemiological Diagnosis and Reference (Indre) Cenavece dependent, has "more than a thousand samples pending" by analyzing the Jalisco, as has been pointed out the authorities of the Ministry of Health (SSJ), and asserted that only 55 are pending analysis of samples dating back days. Among these, three that correspond to the deaths of 7 and May 8 (one of which has already been resolved: see page 7).

The official admitted that it had received more than a thousand samples of suspected cases, "but the majority were negative for this virus." INDRE and gave the official response to Jalisco on the result of more than 500, which included, until yesterday morning, 163 cases of influenza A virus is not new for the A-H1N1.

For its part, the government of Jalisco recognized 411 cases of influenza A still unidentified, that name "probable cases" of A-H1N1, but before May 5 had not been released officially, the existence of this outbreak of influenza A.

- Are two viruses then circulating in group A, the A-H1N1 and we do not know what? -Was asked Lezana Fernandez.

What we have identified, in some states, is one of type A that is flowing from the seasonal period, which is the A-H3N2. This is a seasonal virus that continues to run off-season addition to [...] Jalisco, Zacatecas and Durango, so far.

- Is another virus?

No, no, no. He said: companies are seasonal, are A-H3N2 and human H1N1 are the old people. And I just got confirmed 163 cases in Mexico, so far, which are seasonal.

- Is is possible that a new virus then?

Yes, we have identified the human H1N1 and H3N2. We have no evidence that this is no new virus.

The situation is "very unusual is happening in some states," the director of Cenavece. So unusual for the Epidemiological Surveillance System Jalisco not reported a single case of influenza A in 2008. Nor in 2007. The most recent are for 2006.

On this, the interviewee felt that "these diseases [infection from influenza A] are endemic: they always have been but now is when we detect, because the Epidemiological Surveillance System is more sensitive. It is an assumption that we need to study better, "which already began to do, he said.

The interview was conducted with Lezana at noon yesterday, and the director of Cenavece argued that it had no records of deaths due to influenza A in Jalisco
(afternoon announcement of a: see page 7). Then explained that the three deaths that led to extending the suspension of school activities, and whose results can not come to Mexico, although the Federal Health Secretary Jose Angel Cordova, promised for the May 11 samples, whose studies were " should be repeated, because its outcome was inconclusive. Jalisco 55 samples are pending. "

Jalisco's government has insisted that there is more than a thousand items. You are urged Lezana on the data of samples remaining in the state, and reiterated: "Just the 55".

Lezana found the Jalisco government's decision to extend the suspension of school activities, such as San Luis Potosi, Hidalgo, Guerrero and Michoacan, are decisions made based on local information. I think they were successful in all cases, as just made a good containment. "

He noted that the new cases and hospital admissions for influenza are still declining, and this trend continues, will no longer be a need for social distancing. This can only be known with the passage of days and weeks
